Herrmans H-One S dynamo powered bike headlight

Manufacturer: Herrmans
Brand: Herrmans

Herrmans is a little known (in the US market, at least) Finnish company making some of the best dynamo powered bicycle lights on the market. They may not (yet!) be a household name in the US, but Herrmans was the first company in the world to produce LED-based bicycle lights - way back in 1989! The H-One S is their top of the line headlight; it can stand toe-to-toe with ANY dynamo bike headlight in the world, and will still be standing when the dust clears. As you might expect, it's ready for harsh weather, such as that in Finland where it's manufactured. This is not exaggeration or hyperbole, this thing is BRIGHT. Herrmans measures it at 95 lux (measured at 10 meters at a speed of only 15mph/25kph) without a taillight, while with a taillight they rate it at 75 lux. In other words, extremely bright either way. Another nice feature is the integrated passive reflector, adding yet another "to be seen" capability on top of the 2 LED daytime running light arrangement. In all there are 3 LEDs: the primary super bright headlamp and 2 bright daytime running lights. When your buddies are fumbling on the side of the road looking for spare batteries, you'll be riding with your path completely illuminated, and grinning ear to ear. Once you go dynamo, you never go back to batteries. Cyclists who ride with dynamos the first time usually feel like they've just discovered warp drive, or perpetual motion, and wonder "why haven't I been doing this all along?!" This headlight is best-of-breed, full stop. Note: this headlight has connections for a taillight (sold separately) and requires a dynamo for power (also sold separately).
